1989 Chevy 2500 6 Inch Drop Bracket Suspension
Our first call to action was gaining the appropriate lift required to squeeze in 33-inch tall tires. We took the rig down to RCD Suspension in El Cajon, California, to have their 6-inch drop bracket suspension system installed. Here you can see the difference between the RCD knuckles and the factory units. We like that these knuckles are cast from iron and then CNC machined to ensure perfect steering geometry. These knuckles make up the heart of the RCD system.

1989 Chevy 2500 New Coil Spring
This shot shows the new front RCD coil spring next to the old factory spring. The progressive rate coil springs RCD provides with the system are well-though out and perfectly engineered for our application. These springs are hot wound, shot peened and pre-set (Each coil spring is fully tested and inspected prior to shipment). They are set up to maintain a smooth and comfortable ride while increasing front wheel travel by 20 percent.

1989 Chevy 2500 Twin Link Anti Compression Strut Bars
We were surprised to see both of the included stainless steel "Twin-Link" anti-compression strut bars were beautifully TIG welded to the bushing housings to insure structural rigidity to the front drop down assembly. RCD is the only suspension manufacturer that we know of that goes to that much trouble to make a simple brace look good under the truck.

Here you can see the two heavy-duty steel lower sub-frame assemblies as they were installed under the front of the truck. These assemblies have a durable Polyurethane powder coat finish for long lasting good looks.

The last item RCD installed during the process was the stainless steel "Twin -Link" anti-compression strut bars. These braces triangulate the lower drop down assemble giving it plenty of strength for years of hard bashing.

1989 Chevy 2500 Installing Front Coil Springs
The most difficult part of the suspension installation was installing the front coil springs. The easiest technique to accomplish this in a shop is by combining the compression force of a tranny jack with a few solid blows from a small sledge hammer as shown here. Notice how the RCD technician used a wooden block to protect the coil's finish.

1989 Chevy 2500 Randy Ring And Pinion Kit
After driving the truck, lifted on 33-inch tires, for a few weeks we decided a re-gear was in order. The factory 3.73:1 gearing left the truck feeling a bit sluggish off the line. So we scored a set of 4.56:1 gears for the rear semi-float 14-bolt axle. Randy's Ring and Pinion supplied us everything we needed for the re-gear process, including a master installation kit and the superb Eaton E-Locker differential. We like the E-Locker because it allows the end user the choice of a fully locked or open differential at the touch of a button. The good folks at Right Gear and Axle in Salinas, California, performed the installation in during a brief afternoon visit.

1989 Chevy 2500 Mini Leaf Packs
To attain a more supple rear ride quality we contacted the leaf spring experts at Deaver Spring in Santa Ana, California. After a brief phone conversation about the truck, the Deaver technician recommended that a pair of mini leaf packs be installed in place of the factory overload leafs. A few days later we took a drive to Deaver to have the upgrade performed. This new arrangement allows the spring to flex well while providing a much smoother ride quality. The load carrying capacity was reduced significantly, but that's a trade off we could live with.

1989 Chevy 2500 Softer Rear Spring Arrangement
A full month of driving the truck all over California gave us a pretty good idea of what was needed next. Despite the simplicity of the RCD rear leaf spring blocks, we knew our $500 beater needed a softer rear spring arrangement. The factory overload leaf left the rear suspension firm and even harsh at times.

Tires and Wheels
Our friends at Off Road Warehouse in El Cajon, California, mounted up a set of 33-inch Nitto Terra Grappler A/Ts on Centerline's polished Wolverine wheels. We liked these particular wheels because they are super strong, thanks to their one-piece, rotary forged design. Manufactured to precise tolerances using T-6061 billet aluminum, these wheels feature a 3,200-pound load rating per wheel and come with a 3-year luster warranty. We were impressed that the worst of these tires and wheels only needed 2 ounces of lead to balance out perfectly. That said a lot about how true both the tire and wheels were.

Once fitted to the truck we had RCD do a temporary trim job on the rear corners of the front bumper to prevent rubbing. Soon after we had GM Truck Center in Burbank, California, build us a custom prerunner front bumper complete with winch mount and tabs for auxiliary LED lights.
